IMPROVEMENT IN PLOWS.

To all whom 'zt may concern.-

Be it known that I, GEORGE W. ZEIGLER, of Tiffin City, in the county ofSeneca. and State of Ohio, have invented a new and useful Improvement inFlows; and 1 do hereby declare that the following is a full, clear, andexact description of the construction and operation of the same,reference being bad to the annexed drawings, forming part of thisspecification, in which- Figure 1 is a landside elevation of plow. Fig.2 is atop view. Fig. 3 is a sectional view, showing attachment andadjustment of share. Fig. 4 is an inverted view of plow.

Similar letters of reference in the several fig"- ures denote the samepart.

My invention refers to the regulation of the depth of plowing by themovement of the colter-point vertically. It is designed to effect thisactionindepemlentof both mold-board and share, so as not by its movementto change the form of those parts.

The nature of the invention consists in jointing the colter to the frontof the landside, as will be described, so as to be movable about saidfront of laudside, and between it and the edge of mold-board and share,by lever action upon a. rear arm of the colter, as will be hereinaftersetforth.

1n the drawings, A is the beam; B B, the handles; G, the mold-board; D,the share; E, the landside, and F the colter.

The share is. secured to a base-plate, a, of

mold-board by bolt 1), and is adjusted in position by set-screw c, asshown inFig. 3.

The landside Eis bolted to the base-plate a of the mold-board, a flangeextending inward for that purpose, and is also secured to handle B byboltd. Thetrontextremity,e,ofthe landside is divided vertically, so asto lap upon the colter F, as shown in Figs. 1 and 4, the end of thelandside being rounded, and the outside of colter hollowed to receivesaid. front part. of landside. The bolt f, passed through landside andcolter, connects the two by a firm lap-joint, the colter being capableof movement about said bolt.

The colter is constructed with an arm, g, extending rearward,as shown inFig. 1, and has in its rear extremity an inclined slot, i, in which isinserted the arm at of the rock-shaft Z, turning in box a on the side ofbeam A by power applied to lever 19. This lever is held in position bynotches on top of cross-bar h, between the handles B B. The side r ofcolter rests against the mold-board and share, and makes with them aclose joint without being in any way secured to either.

From the above description it will readily be seen that by moving lever17 toward handle B arm on of shaft 1 will be moved in slot 1', pressingagainst the upper face of said slot, turning the colter about bolt f bylifting arm g, and consequently depressing point q of the colter. Theopposite movement lifts the point. This movement of the colter isaltogether independent of both mold-board and share, and is e."- fectedwithout altering the form of either.

The mold-board, colter, and share may be coustructedof anyot' thewell-known materials used for this purpose, and the details of the otherparts ot'the plow may be varied in many ways, so long as the inventionhere claimed is not affected by such alteration.

I am aware that Harrison Norton obtained a patent, dated October 9,1855, by which he regulated the depth of the furrow by a movableplow-point acting upon the same principle as that shown in myspecification. I do not claim, therefore, to have been the lirst toinvent that method of accomplishing this object; but

What 1 do claim as new, and desire to secure by Letters Patent, is-

Simplyan improvement upon the invention of Norton, such as is set forthin the foregoing s1')ecitication-thatis to say, by combining withlandside and mold-board a colter, F, jointed to the landside, asdescribed, and movable between landside and mold-board independent ofthe mold-board and share.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses.

GEORGE WV. ZEIGLER.
